Title: Phase locked loop circuit
Inventor: KOJIMA TADASHI
IPC: H03L7/14
Filed: 1979-10-13
Abstract: PURPOSE:To make it possible to exercise phase control rapidly and securely by providing a means of permitting voltage control oscillating circuit VCO to oscillate at the same frequency with a synchronizing signal in the middle of a variable frequency in a free-running state. CONSTITUTION:When a video signal is inputted to input terminal 32 and a vertical synchronizing signal is separated by synchronous separating circuit 34, this signal is inputted to monostable multivibrators 36 and 38 and switches S1 and S2 are controlled to sample the output signal of the sawtooth wave generation part. The sampled signal is passed through sample holding part 44 and LPF48 to control VCO50. The output of VCO50 is frequency-divided by frequency divider 52 and the PLL circuit is constituted via FF54 and monostable multivibrator 56, so that VCO50 will oscillate synchronizing with the vertical synchronizing signal. When the supply of the v ideo signal to input terminal 32 is stopped, monostable multivibrator 38 controls switch S2 with a signal from output Q' of FF54 to sample a saw-tooth wave signal, so that VCO50 will be made to oscillate at a stable frequency. While VCO50 is in the free-running state, semifixed coil VL and capacitor VC are previously adjusted to synchronize with the vertical synchronizing signal, so that synchronization can be attained rapidly.

Title: Door lever handle
Inventor: KURIKAWA NORIYUKI
IPC: E05B3/04
Filed: 1999-05-13
Abstract: PROBLEM TO BE SOLVED: To provide a door lever handle installed on both sides of a door surely and very easily according to a thickness between the both sides of the door. SOLUTION: When a square core member 6 is fitted into a through hole 14, the square core member 6 is fitted into the through hole 14 while exerting a force against an end plate 13 in the direction (arrow direction of P) that an inclination angle of a base plate 12 relative to the end plate 13 is increased against the elastic force of the end plate. Accordingly, the centerline of the through hole 14 comes near the state of being aligned with the center axis of the square core member 6, and the square core member 6 is inserted smoothly into a recessed hole 7. When the inserted square core member 6 is tried to be extracted, the engagement of the through hole 14 with the square core member 6 locked to the through hole provides a force through the square core member to the end plate 13 in the direction of arrow Q. As a result, the centerline of the through hole 14 is displaced largely from the center axis of the square core member 6, and the engagement becomes more tight and the square core member becomes more difficult to be extracted from the through hole. This is established when a coefficient of friction at the contact portion of the square core member 6 with the through hole 14 meets the specified requirements.
